I can accpet a lot of things, but tyres going off, well, i'm not having that one.

Sorry Steve but you'll have to swallow it. Lap 5 & 6 of almost every race see the back end sliding. It's not a matter that they go off, more that the top layer of rubber overheats while the carcass is still cold (a consequence of having no tyre warmers). The difference in temp causes the tyres to feel greasy and lose traction. What they'll be like over 12 laps of a hot donny I dread to think. There isn't a road tyre on the market that's designed to run at race pace for 25 mins at a track temp of 45 degs C, let alone the humble (but brilliant) Diablo.

As for you running back to back sessions on the 916, try carrying some cornerspeed once in a while and you'll soon see what we're on about.......
